IMPROVEMENT IN AUTOMATIC FANS.

To all whom 'it may concern:

Be it known that I, EDWARD D. SwARTWoUT, of Chicago, n the State ofIllinois, have invented certain Improvements Combining a Fan or Aire Agitator with a Bedstead, of which the following is a specification:

The nature ofmyinvention consists in combining afan with a bedstead,arranged in such a manner that the fan shall be caused to revolve orvibrate by means of clockwork and agitate the air immediately over thebed, substantially as is hereinafter set forth.

Referring to the drawing, Figure 1 is a perspective view of a fan andbedstead.

The bedstead may be of anyT known construction, the head-board A and thefoot-board A2 being a support, and from which is suspended the shaft B7and in ease either the head-board or the foot-board is not of sufficientheight, uprights M may be used as a support to the shaft B above thehead-board or the foot-board, as sh own in the drawing. One end of theshaft B is pivoted at a to the headboard A, and the other end is pv'oted to the footAboard A2 or to its upright M, as shown. The shaft B isprovided with cross-arms 2 near each of its ends, and there may be moreor less arms, and there may be, or may not be, arms at the center of theshaft. To the arms 2 2 I secure the blowers or air-agitators K. I preferto use for the blowers a thin close-woven cloth, but any proper materialmay be used, and may be attachedgto the arms 2 in any proper manner.Near one end of the shaft B I secure a cog-wheel, E, which is gearedinto a cog-wheel of the clockwork W. The clock-work W may be .any commonclock, or a train of more or lesswheels driven by a spring or a weight,and the clock-Work is so. arranged and situated that one of its wheels,or an auxiliary wheel, shall mesh or gear into the cog-wheel E.

ln operation the clock-WorlrW imparts motion to the shaft B, causing itto revolve, carrying round the blowers K, agitating the air immediatelyover the bed. The shaft B may be caused to revolve at any desired speedby the proper adjustment and size of the Wheels in the clockwork and ofthe Wheel E, producing a slow motion to agitate the air, or a fastmotion to fan persons lying on the bed.

Mosquito-bars and curtains may be used around and over the bedstead, andthe air over the bed is kept constantly in motion from evening untilmorning.

I claim- In combination with a bedstead, the bearingshaft B, supportedat the head and the foot of the bedstead, and to which is attachedblowers K, constructed and arranged to operate with the clock-work,substantially as shown, whereby the blowers are caused to revolve or tovibrate and agita-te the air immediately over the bed, all constructedand arranged relatively to each other, substantially as shown and forthe purpose set forth.
